Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an anti-condensation radiation air conditioning terminal and a radiation air conditioning. Background Art

[0002] Currently, to prevent condensation on the radiating components of radiant air conditioners and improve radiant cooling capacity, existing technologies employ infrared-transparent film to seal an air layer over the radiant cooling surface. This film replaces the radiant cooling surface as the air contact surface, physically separating the radiant cooling surface from the air contact surface. This creates an air layer between the air contact surface and the radiant cooling surface, creating a temperature difference that prevents condensation. The thermal resistance of the air layer allows independent control of the radiant cooling surface and air contact surface temperatures, thereby increasing the air contact surface temperature while simultaneously reducing the radiant cooling surface temperature, ultimately improving cooling capacity.

[0003] Existing radiant air conditioning terminals are installed on indoor ceilings. Although the infrared transparent film can effectively prevent condensation and improve the radiant cooling capacity, when there is an external object pushing the transparent film, the external transparent film has poor pressure resistance and the infrared transparent film as a whole will undergo a large tensile deformation. After the external object is removed, the deformed part of the infrared transparent film will droop downwards, greatly affecting the appearance of the radiant air conditioning terminal. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-condensation radiation air-conditioning terminal and a radiation air-conditioning, aiming to solve the technical problem that after the existing infrared transparent film is squeezed and deformed by external objects, the deformed part of the infrared transparent film droops downward, affecting the appearance of the radiation air-conditioning terminal.

[0005] To achieve the above-mentioned purpose, the anti-condensation radiation air conditioning terminal proposed in the first aspect of the present invention includes:

[0006] A radiation member having a radiation surface; the radiation member is provided with a frame, the frame being arranged to protrude relative to the radiation surface;

[0007] An infrared transparent bubble film comprises a base film and a plurality of bubbles protruding from a surface of the base film, wherein the bubbles have independent air chambers, the base film is sealed to the frame, the bubbles are located on a side close to the radiation component, and the bubbles abut against the radiation surface.

[0008] Optionally, an infrared anti-reflection coating is provided on the surface of the base film away from the bubbles.

[0009] Optionally, the radiation member includes a radiation plate.

[0010] Optionally, the radiation component also includes a phase change energy storage unit, which includes a phase change material layer and two metal plates, the phase change material layer is encapsulated between the two metal plates, one of the metal plates is arranged face-to-face on one side surface of the radiation plate, and the other metal plate's side surface away from the phase change material layer is the radiation surface.

[0011] Optionally, the infrared transparent bubble film has an average transmittance greater than 0.6 in the infrared band of 2.5 to 22 μm.

[0012] Optionally, the thickness of the base film at the gap is 90-150 μm.

[0013] Optionally, the bubble height is 6 to 12 mm, and the bubble diameter is 12 to 28 mm.

[0014] The second aspect of the present invention discloses a radiation air conditioner, comprising the anti-condensation radiation air conditioner terminal described in the first aspect of the present invention.

[0015] The technical solution provided by the utility model may have the following beneficial effects:

[0016] In the present invention, the base film of the infrared-transparent bubble film is sealed to the frame, physically isolating the gaps between the bubbles from the outside air. This effectively prevents cold, moist air from contacting the radiating surface through the gaps between the bubbles and causing condensation. Furthermore, each bubble has an independent air chamber to store air, which, combined with the air in the gaps between the bubbles, creates a closed air layer between the radiating surface and the base film. This creates an air-contact surface on the side of the base film facing away from the radiating element, physically separating the radiating surface from the air-contact surface. The air layer formed between the air-contact surface and the radiating surface creates a temperature difference, preventing condensation.

[0017] In the present invention, the bubbles of the infrared transparent bubble film abut the radiating surface. When an external object pushes against the infrared transparent bubble film, the bubbles provide support and cushioning, hindering the inward compression deformation of the infrared transparent bubble film's base film to a certain extent. This improves the compressive strength of the infrared transparent bubble film compared to existing infrared transparent films, reducing tensile deformation caused by external forces. This prevents the base film from drooping after tensile deformation, minimizing the impact on the appearance of the radiant air conditioner terminal. Furthermore, the base film of the infrared transparent bubble film also exhibits better tensile strength than existing infrared transparent films, reducing the risk of damage to the air layer structure and ensuring anti-condensation effectiveness.

[0029] The following combination Figure 1 The anti-condensation radiant air conditioning terminal shown includes:

[0030] The radiation member 100 has a radiation surface 110; the radiation member 100 is provided with a frame 120, and the frame 120 is arranged to be raised relative to the radiation surface 110; specifically, the frame 120 is sealed to the radiation member 100, and the frame 120 can be arranged around the edge of the radiation member 100. Of course, in other embodiments, the frame 120 can also be arranged on the radiation surface 110.

[0031] The infrared transparent bubble film 200 includes a base film 210 and a plurality of bubbles 220 protruding from a surface of the base film 210. The bubbles 220 each have an independent air chamber. The base film 210 is sealed to the frame 120. The bubbles 220 are located on a side close to the radiating member 100 and abut against the radiating surface 110. In a specific embodiment, the infrared transparent bubble film 200 may be a polyethylene bubble film.

[0032] Specifically, the base film 210 of the infrared-transparent bubble film 200 is sealed to the frame 120, physically isolating the gaps between the bubbles 220 of the infrared-transparent bubble film 200 from the outside air. This effectively prevents cold, moist air from contacting the radiating surface 110 through the gaps between the bubbles and causing condensation. Furthermore, each bubble 220 has an independent air chamber to store air. This, combined with the air in the gaps between the bubbles 220, creates a closed air layer between the radiating surface 110 and the base film 210. This creates an air-contacting surface on the side of the base film 200 facing away from the radiating member 100, physically separating the radiating surface 110 from the air-contacting surface. The air layer formed between the air-contacting surface and the radiating surface 110 creates a temperature difference, preventing condensation.

[0033] In the present invention, the bubbles 220 of the infrared-transparent bubble film 200 abut the radiating surface 110. When an external object pushes against the infrared-transparent bubble film 200, the bubbles 220 provide support and cushioning, somewhat hindering the inward compression deformation of the base film 210 of the infrared-transparent bubble film 200. This improves the compressive strength of the infrared-transparent bubble film 200 compared to existing infrared-transparent films, reducing tensile deformation caused by external forces. This prevents the base film 210 of the infrared-transparent bubble film 200 from sagging after tensile deformation, minimizing the impact on the appearance of the radiant air conditioner terminal.

[0034] In addition, the bottom film 210 of the infrared transparent bubble film 200 has better tensile strength than existing infrared transparent films, which can reduce the risk of damage to the air layer structure and ensure the anti-condensation effect.

[0035] Specifically, the infrared transparent bubble film 200 and the infrared transparent film were subjected to tensile tests. The tensile test adopted the GB / T1040 "Determination of tensile properties of plastics" standard and used an electronic universal testing machine (CMT6000) to conduct 5 tensile performance tests on polyethylene bubble film A, polyethylene bubble film B, polyethylene bubble film C, and polyethylene film. The tensile speed was 100 mm / min. The polyethylene film was a polyethylene film with a thickness of 20 μm purchased on the market. Figure 5 The specifications and dimensions of polyethylene bubble film A, polyethylene bubble film B, and polyethylene bubble film C are shown in Table 1 below:

[0036]

[0037] Tensile test results showed that the maximum tensile strengths of polyethylene bubble film A and polyethylene film were 22.15N and 9.70N, respectively. Polyethylene bubble film A showed a 128% improvement in tensile strength compared to polyethylene film. Polyethylene bubble film B and polyethylene bubble film C showed a 183% and 223% improvement in tensile strength, respectively, compared to polyethylene film. This demonstrates that infrared-transparent bubble film 200 exhibits superior tensile strength compared to infrared-transparent film, meaning it is less susceptible to tearing and more effectively prevents the air layer from being destroyed.

[0038] like Figure 2 In the illustrated anti-condensation radiant air conditioner terminal, the surface of the base film 210 facing away from the air bubbles 220 is provided with an infrared anti-reflection coating 230. In this embodiment, by providing the infrared anti-reflection coating 230 on the side of the base film 210 facing away from the air bubbles 220, infrared transmittance is increased, thereby facilitating better radiative heat transfer from the radiant terminal. Specifically, the infrared anti-reflection coating 230 can be any of aluminum oxide, barium fluoride, zinc sulfide, polyethylene terephthalate, polydimethylsiloxane, or polymethyl methacrylate.

[0039] like Figure 3 In the illustrated anti-condensation radiation air conditioner terminal, the radiation component 100 includes a radiation plate 130. In this embodiment, one side surface of the radiation plate 130 serves as the radiation surface 110, and the air bubbles 220 abut against the side surface of the radiation plate 130 serving as the radiation surface 110.

[0040] like Figure 4 In the anti-condensation radiation air-conditioning terminal shown, the radiation component 100 also includes a phase change energy storage unit 140, and the phase change energy storage unit 140 includes a phase change material layer 141 and two metal plates 142. The phase change material layer 141 is encapsulated between the two metal plates 142, one of the metal plates 142 is arranged face to face on one side surface of the radiation plate 130, and the side surface of the other metal plate 142 away from the phase change material layer 141 is the radiation surface 110.

[0041] In this embodiment, a phase-change energy storage component is provided on the radiating surface 110 of the radiating member 100 to store energy. When the cooling capacity exceeds the required indoor cooling load, the phase-change material solidifies and stores the cooling capacity. When the cooling capacity falls below the required indoor cooling load, the phase-change material melts, releasing the cooling capacity and simultaneously providing cooling to the room with the radiating member 100. Specifically, in some embodiments, the phase-change material layer 141 can be an existing calcium chloride hexahydrate-mannitol / silicon dioxide shaped composite phase-change material.

[0042] As an optional embodiment, the infrared transparent bubble film 200 has an average transmittance greater than 0.6 in the infrared band of 2.5 to 22 μm. In this embodiment, by limiting the average transmittance of the infrared transparent bubble film 200 to greater than 0.6 in the infrared band of 2.5 to 22 μm, the optical performance of the infrared transparent bubble film 200 is ensured, and the infrared transmittance of the infrared transparent bubble film 200 is prevented from being too low, thereby affecting the cooling capacity of the radiant air conditioner.

[0043] As an optional embodiment, the thickness d4 of the base film 210 at the gap is 90 to 150 μm. The greater the thickness of the base film 210, the better the tensile strength of the infrared transparent bubble film 200 will be, making the air layer structure less likely to be destroyed, thereby effectively achieving the anti-condensation effect. However, the greater the thickness of the base film 210, the worse the infrared transmittance will be, and the radiant cooling effect will be reduced. Conversely, the smaller the thickness of the base film 210, the weaker the tensile strength of the infrared transparent bubble film 200 will be, making the air layer structure relatively easy to be destroyed, thereby affecting the anti-condensation effect. However, the smaller the thickness of the base film 210, the greater the infrared transmittance will be, and the radiant cooling effect will be better. After multiple data tests, the thickness d4 of the base film 210 at the gap of the infrared transparent bubble film 200 is preferably in the range of 90 to 150 μm, with good tensile strength and a small reduction in the radiant cooling effect.

[0044] As an optional embodiment, the height of the bubble 220 is 6 to 12 mm, and the diameter of the bubble 220 is 12 to 28 mm.

[0045] A second aspect of the present invention discloses a radiant air conditioner, including the anti-condensation radiant air conditioner terminal described above. Specifically, in some embodiments, the radiant air conditioner includes a chiller and a cold water pipe, the cold water pipe being coiled and disposed on a surface of the radiant member 100 away from the infrared transparent bubble membrane 200, and the chiller being connected to the cold water pipe.

[0046] In the radiant air conditioning terminal, the base film 210 of the infrared transparent bubble film 200 is sealed to the frame 120, physically isolating the gaps between the bubbles 220 of the infrared transparent bubble film 200 from the outside air. This effectively prevents cold, moist air from outside from contacting the radiating surface 110 through the gaps between the bubbles and causing condensation. Furthermore, each bubble 220 has an independent air chamber to store air. This, combined with the air in the gaps between the bubbles 220, creates a closed air layer between the radiating surface 110 and the base film 210. This creates an air-contact surface on the side of the base film 200 facing away from the radiating element 100, physically separating the radiating surface 110 from the air-contact surface. The air layer formed between the air-contact surface and the radiating surface 110 creates a temperature difference, preventing condensation.

[0047] In the present invention, the bubbles 220 of the infrared-transparent bubble film 200 abut the radiating surface 110. When an external object pushes against the infrared-transparent bubble film 200, the bubbles 220 provide support and cushioning, somewhat hindering the inward compression deformation of the base film 210 of the infrared-transparent bubble film 200. This improves the compressive strength of the infrared-transparent bubble film 200 compared to existing infrared-transparent films, reducing tensile deformation caused by external forces. This prevents the base film 210 of the infrared-transparent bubble film 200 from sagging after tensile deformation, minimizing the impact on the appearance of the radiant air conditioner terminal.

[0048] In addition, the bottom film 210 of the infrared transparent bubble film 200 has better tensile strength than existing infrared transparent films, which can reduce the risk of damage to the air layer structure and ensure the anti-condensation effect.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present invention.
